About Libre

Libre embodies the spirit of the Polar Information
Commons (PIC). We are growing a collaborative polar community by fostering open data sharing. Data sharing is vital to the interconnectedness that characterizes today's research questions. To that end, we offer tools and services that make data sharing and access easy. We've figured out the data sharing technology and tools, so you don't have to.

Norms for Knowledge and Data Sharing

Give the appropriate recognition to the PIC as a digital community resource in their publications and value-added products and services.

Notify the relevant PIC contributors (or the PIC community more generally) about their use of specific digital materials from the PIC, and about any suspected significant errors, limitations, or other problems that they may have discovered in the course of their use of those materials.

Acknowledge that they are primarily responsible for determining whether the PIC materials they use are of sufficient quality and appropriateness for their objectives.
